The hottest innovation in medicine may also be the cure for aging skin. But is it safe? Ever since doctors performed the first stem cell transplant in the late 1950s, the so-called blank-slate cells have held a promise that seems almost too good to be true: human body cells that can heal and perhaps cure what ails us. In the intervening decades, stem cell transplants have been used on thousands of cancer patients and are being hailed as a potential cure for Parkinson’s disease, paralysis, and in a new twist, aging skin. As stem cell skin care hits store shelves with claims it can quickly erase wrinkles, we investigate what we know – and what we don’t – right now.
